7 Claims. l

This invention relates to faucets and particularly to such faucets asare commonly employed in connection with wash stands or the' like forcontrolling the flow of water thereto.

Such faucets commonly comprise a body formed of a single casting, theexterior surface of which is polished to provide a smooth and pleasingappearance. A body formed in this way is subject to the usual hazards ofcastings such as porous spots, blow holes and the like so that at leastsome of the castings must be rejected. While some defects may be such asto render a casting entirely useless by causing it to leak, otherdefects may be only surface flaws, but nevertheless, the casting must berejected since it cannot be nished in an acceptable manner. Defects arenot always apparent in a rough casting, but are often uncovered in amachining or polishing operation, sometimes after considerable work hasbeen performed, in which case not only is the casting lost, but the restof such work as well.

It is an object of this invention to provide a faucet so constructedthat the number of castings required to be rejected in accordance withthe foregoing is substantially reduced.

It is another object of this invention to provide for this purpose afaucet having a built-up body fabricated from parts, some of which maybe castings and others of sheet or bar stock.

It is another object of this invention to provide a faucet having abuilt-up body, including a pair of uid conducting parts, only one ofwhich is subjected to fluid pressure. In this way the number of partswhich must be rejected as defective is substantially reduced.

It is another object of this invention to provide a faucet wherein thatportion of the body subject to pressure comprises a separate piece,hidden from view, and thus does not require polishing.

Hence, the possibility of such parts requiring to be rejected fordefects uncovered by a polishing operation is limited. Further, the onlyportion a polished member of sheet or tubular materialy for covering atleast a part of the body. A

It is still another object of this invention to provide a built-upfaucet body which may be easily assembled.

This invention possesses many other advantages, and has other objectswhich may be made more clearly apparent from a consideration of oneembodiment of the invention. For this purpose there is shown a form inthe drawings accompanying and forming part of the present specication.The form will now b e described in detail, illustrating the generalprinciples of the invention; but it is to be understood that thisdetailed description is not to be taken in a limiting sense, since thescope of this invention is best` dened by the appended claims.

In the drawing:

Figure 1 is a vertical section, partly in elevation, oi a faucetincorporating the features of the i invention; and

Fig. 2 is a pictorial exploded view of the body of the faucet.

Referring to Fig. 1 of the drawing, a faucet I is shown having agenerally conventional appearance and mounted in an opening 2 in a wall3, which may be part of a conventional wash stand. The faucet is to beconnected in the usual way to a supply pipe (not shown).

The body of the faucet l comprises a tubular member 5 and a spout 6secured thereto. The member 5 is preferably of circular cross section,having a running thread along its lower end, as indicated by E-o, andhaving an enlarged portion or head 'l at its upper end which provides adownwardly directed shoulder l-a facing the wall 3.

The spout 6 projects from an integral cylindrical chamber 8 which istelescoped over the head 'l and is provided with an inwardly directedflange B-a adapted to engage the shoulder 'l-a. The upper portion of thehead l is enlarged and exteriorly threaded as indicated by 'l-b. Theupper end of the chamber 8 is of reduced diameter and is correspondinglythreaded at B-b, to

engage the lower end of the threaded portion 'l-b.

The spout t is assembled on the member 5 by threading it on from belowuntil the flange 8-a and shoulder 'l-a are in engagement, a suitablewasher l2 being interposed between the flange and the shoulder toprevent leakage. A iianged ,I sleeve or spacer I4 is telescoped over thebody member 5 and is clamped between the ilange 8-a 3 and the wall 3 bya nut I5 threaded on the member 5. In this way the faucet is secured tothe wash stand wall 3.

The axial bore through the member 5 is reduced to provide a valve seatI6 within the head 'I and is enlarged in diameter and provided with acoarse threadv Il for accommodating a correspondingly threaded ,valveclosure I8. This closure I8 has a stem I9 projecting from the member 5and carrying an operating handle 2li. Packing means 2l is provided aboutthe stem I9 and is confined in a packing nut or gland 22 which is Ithreaded on the upper part of the threaded portion 'I-b of the head I.Rotation of the closure IB by means of the handle 2D serves to open andclose the faucet in an obvious manner.

The member 5 is the only portion of the body subjected to iiuidpressure. This member may be conveniently made from a casting, barstock, or a die casting; and, since it is substantially entirely hiddenfrom view by the sleeve I4 and chamber B, it does not require polishing.Hence, no castings are rendered defective by such an operation. On theother hand, spout 5 which does require polishing is not subjected to uidpressure, and hence, less perfect castings can be tolerated. Anadditional advantage of the separate sleeve or flange Ill is that it canbe formed vof sheet or tube stock, as by a spinning or stampingoperation; such material is much more easily polished than a casting.

In assemblying the faucet, the spout il is secured to member 5 byscrewing the portion S Vonto the head l until the flange a-a engages theshoulder 'I-a, the gasket I2 being interposed. The sleeve Iii is vthentelescoped over the member 5, and the member 5 inserted in the opening2. The nut I5 is then screwed into the threaded portion -a, securing thefaucet I to the wall 3 by clamping the sleeve Ill between the wall andthe flange S-d. The valve closure I 3 and the Apacking means 2l, 22, maybe assembled in the member 5 either before or after mounting the spout 5on the member, and may be subsequently removed at any time forinspection and repair.
